Thank Congress and the ones who pushed through the alcohol mess. The producers hands are tied.
You would not want to pay for the elastomer compound which is impervious to alcohol, oil, heat, combustion byproducts, and fuel. Attacking seals is but one of the problems caused by alcohol. Welcome to the green world where nothing else matters. A standard material O-ring which sell for a dollar or two would cost over $100 in that magic compound. I have sold a small box of those for more than your motor cost.
Bearings, seals, and elastomers were how I made my living, and I have dial indicated more bearing frames over the years than you would believe. There is always play in a bearing assembly, but it is small. If you can feel the play, the bearing is not long for the world. Now let vibration or lack of lubrication cause a pit in a bearing and it will destroy itself in use by transferring pits inside the bearing. The worst culprit we deal with now are trailer wheel bearings which sit up for months at a time. Due to hardness requirements, bearings are not made of stainless materials as a general rule and a fingerprint can ruin one. They are protected by a thin film of lubricant normally and maintaining the lube is exceedingly important. Alcohol really helps - not.
